To all 'whomie't may concern: 7 7

Be it known-that I, THoMAs. C. :MORRIS, a

' citizen of the United States, residiugat city of Atlanta, county of Fulton, and State of Georgia,.have inventeda certain new and useful Improvement in Mountings'for 1F eedlug-Rollers, of which the following is a full, clearyand exact description, such as will enable othersskilled in the art'to which it appertainsto make and 'us'ethe'same, reference beingihad to the accompanyingdrawings, forming part of .thisspecification.

" This zinventionrelates to certain improvements in feed rollers. forlumber machines of the type 'illustratediin :the patent to Thomas A. Coleman, No. 1,208,294..

As is well known inthe art, rollers of thetype commerciallyknown asthe Coleman feed rollers are characterized I by a construc tion which is designedto facilitate the installation-ofthe roller, and its repair, without necessitating its removal'from the machine. The Coleman ,lconstruction includes a'shaft which is journaled in the machine, and upon which are mounted one ior'more drums'or carriers in which are removably seated the engaging elements or *tooth'b'ars, the same being retained-'inrtheir seatsby the clamping action of relatively adjustable members which cooperate with-their extremities. These rollers'are frequently sold to V replace, in machines already installed, rollers of other types. V

The purpose of my invention is to improve or. add to the Coleman construction in certain particulars whichwill enable it'to meet 7 certain conditions obtaining in machines designed for other sorts of rollers. TheCole man construction requiresthat the carriers be adjustable longitudinally on the shaft so' 7 as to facilitate the removal of the engaging elements; This necessitates the intermediate portion ofthe shaft being' larger than the end portions, in order that the drums or.

carriers maybe slipped onto the shaft; In

many machines designed for other forms of rollers, however,the bearings or boxes in which the shaft is journaled, are of considerably greater diameter than that" permitted in a Coleman roller of the desiredsi'ze; The present improvement is; designed to provideanarrangement wherebythe journal portions of the shaft may be equipped for .mounting in bearings of excessive size. The

present improvement contempl e furth r the provision of a construction Whereimin a roller-so equipped, the screwthreads upon which the. adjustable terminal clamping member is mounted, are protected from injury, and the roller'in its entirety is held against longitudinal movement in its bearings. 1

Other and further objects will be obvious or pointed out hereinafter, reference being had to the accompanying drawings, in which-' 1 Figure 1 is a detail in the nature ofa' parthe customary longitudinal slots 4 for the reception of the tooth bars or-engaging elements 5. 7 7 drum the shaft is provided with the screw thread 6 upon which the clamping'collar' 7 is mounted for .movable cooperation with the extremities of the tooth bars 5 and the adjacent drum 2. When turned up, :the clamping collar 7 engages the drum 2 and Adjacent the extremity of the theextremities of the tooth bars in the manner characteristic of the Coleman feed roller;

and said clamping collar maybe'baoked V away from the drum to clear theextremities of the tooth "bars to permit their removal portion of the shaft whichl designate by the numeral 71* "extends beyond the screwthreaded' portion and, necessarily, is of less diameter than the screw-threaded portion and the portion which supports the drum's2.

In order to accommodate this journalpor= tion of the shaft to'a box or bearing, is frequently necessary in a machine'not de signed specially "for the mounting of the Coleman feed roller, I'apply on thejournal portion 1 a bearing sleeve 8. This sleeve is driven over the journal portion 1 and is. turned on to the screw-threaded portion 6 to the desired extent, leaving the necessar from-the slotswhenso desired; The journal clearance between the "inner extremitv 'of thesleeve and the adjacent face of the clamp: ing collar. 7 to permit the required outward "m ent f th at er.- The "sleeve I s then turned down on itsouter face to the proper diameter for installation in the bearing 9. In conjunction with this arrangement, for the purpose of retaining the shaft against longitudinal movement in the bearings, and to afford the necessary protection for the screw threads 6, I provide a bearing collar 10 which is rotatably mounted upon the bearing sleeve 8. This bearing collar has a bearing face 10* extending normal to the shaft and adapted to contact with the adj acent face of the hearing or box. The bearing collar 10 is counter-bored from its other face to accommodate a shoulder 8- formed adjacent the inner extremity of the bearing sleeve 8, the arrangement operating to hold the bearing collar 10 against movement in? wardly on the shaft toward the clamping collar 7. Seated in the bearing collar 10 are one or more dowels 11 which extend inwardly and have adjustable cooperation with the clamping collar 7 by means of the channels 12 arranged in the latter for the reception ofthe dowels. The clamping collar 7 is provided with the customary spanner seats 7 whereby it may be engaged to be turned on the, screw thread 6. -When it is desired to back off the clamping collar to release the engaging elements, the bearing collar 10 will be rotated with the clamping collar by virtue of'the engagement of the dowels in the channels 12, while the extent of said channels will permit the movement of the clamping collar toward the bearing collar. Flush with its outer face the clamping collar is provided with the annular flange 14 which extends about the perimeter of the bearing collar 10, forming a close sliding fit therewith, and affording a complete cover and protection for the portion of the screw thread 6 intermediate the collars.

As a means for preventing longitudinal movement ofthe shaft away from the bearing, I extend the journal portion 1 beyond 1; the outer extremity of the bearing or box,

and there aflix to the shaft the set collar 15, same being held by a counter-sunk set screw 16. The set collar 15 has its inner face normal to the shaft and adapted to bear against the outer extremity of the bearing 9, by

V virtue of which engagement the shaft is retained against longitudinal movement in wardly from the hearing. I

It will be understood that by virtue of this arrangement of parts the roller may be accommodated to a wide variety of boxes or bearings, as, irrespective of the over-all diameter of the operating portion of the roller, the diameter of. the journal portion maybe varied as required. Furthermore, by variations in the width of the bearing collarlO, and by virtue of theadjustability of the set collar 15, the roller may be ac- V Copiss 0. this patent may be obtained for five w mm a we a Washington, D. 0. V

commodated to bearings or boxes of any width. The arrangement of bearing collar, clamping collar, and bearing sleeve, also affords complete protection to the thread upon which the clamping collar must operate, preventing its injury in any such fashion as may interfere with the facilities for permitting the removal and replacement of the tooth bars. 7

Inasmuch as the dowels hold the clamping collar and the bearing collar for rotation together on the shaft, the operative engagement of the bearing collar .withfthe face of the bearing will act to keep the clamping collar screwed up tight, it being understood that the thread on the shaft is pitched to- Ward the bearing. V r Other advantages of this construction will be readily apparent to those skilled in'the art, as will various modifications and adaptations of the particular arrangement shown. It is my purpose and intention in the following claims to comprehend all of [such various modifications and adaptations as are properly within the true scope and spirit of my invention. V v

In a feeding roller including the shaft, the drum carried thereby, and the clamping collar having screw-thread engagement with the shaft in association with the drum, the combination of a bearing sleeve mounted on the shaft in association with the clamping collar, and formed to provide a journal for the shaft, and means associated with said bearing sleeve for engaging a bearing in which the shaft is journaled to preventiongitudinal movement of the latter. 1

2. In a feeding roller including the shaft,

the drum carried thereby, and the clamping collar having. screw-thread engagement with the shaft in associationwith the drum, the combination of abearing sleeve mounted on the shaft and shaped to form a journal for the shaft,and means associated with said sleeve to prevent contact of the, screws threaded portion of the shaft with a'bearing in which the shaft is journaled. r
